Hi everyone. Have you managed to install Qt 5 on Linux? I have tried to install Qt 5 RC2 but I have received this error message./qt-linux-opensource-5.0.0-rc2-x86_64-offline.run: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.15' not found (required by ./qt-linux-opensource-5.0.0-rc2-x86_64-offline.run)
